To 'all whom t may concern:

Be it known that I, LOUIS Sounnmnn, a citizen of the United j States, residing at Hol-land, in the county of @ttawa and State of Michigan, have invented certain new and useful Improvements in Spring-Seats, of which the following is a specification.

' This invention relates. to spring seats particularly adapted for use in automobiles, railway cars, carriages, and other vehicles.

An object of the invention is the production of a spring supported seat and back movable as a unit.

A further object is the provision of a seat and back movable on vertlcal guides to permit the seat to move independently of the motion of the vehicle, and thus absorb the shocks and jars incidental to the travel of the vehicle over a roadway.

A further object is the provision of means for adjusting the tension of the supporting springs.

ln the accompanying drawings, I have I shown one embodiment of the invention. In

this showing: A

Figure 1 is a front elevation of a seat frame,

Figure 2 is a vertical sectional view on line 2-2 of Figure 1,

Figure 3 is a horizontal sectional view on 3, passing through flanges 4, rformed at the' ends of the bracket. The bottom 5 otthe seat is supported above these brackets by means of coil springs 6. These springs are received in spring cups 7 carried on the under side of the bottom of the seat, the other end of the springs being receive'din similar cups 8 arranged on the top of the brackets. The cups 8 are provided with threaded openings for the reception of threaded rods 9 passing through threaded openings in the brackets 2. rFhe threaded rods are provided with suitable heads 10. A cushion 11, shown in dotted lines, may be arranged on the bottom of the seat in lAs shown, the back is provided with brackets 15, each of which is provided with an od'- set portion 16 adapted to-embrace the arms 17 of the 'IF-shaped guide. rlhe bracket is provided with openings on opposite sides and ears 18 are arranged adjacent the openings. Rollers 19 are mounted on suitable shafts 20, the shafts beingjournaled in the ears 18 and the rollers passing through the openings in the sides of the bracket and engaging opposite sides of the arms 17. rlhe outer face of the odset portion 16 o the bracket is also provided with an opening arranged below the horizontal plane of the rollers 19. Suitable bearings 21 arearranged adjacent this opening and a roller 22 is mounted on the shaft or pin 23, supported in the bearings 21, the roller engaging the front of the arm 17. From the above description, it will be apparent that the seat and back are vertically movable independent of the movement of the vehicle in which the seat is used. The vertical guides maintain the seat and back in proper position at all times. The provision of rollers engaging three sides-oirl the vertical guides prevents the parts from becoming displaced, and the arrangement of one roller in a horizontal lplane beneath the plane ot. the other two rollers prevents side play. The tension ot the springs 6 may be adjusted as desired by moving the cupstvertically, as indicated in /dotted lines in Figure 2 of the drawings.

A1t is to be understood that the form of the invention herewith shown and described yis to be taken as a preferred example of the same, and that various changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.

aving thus described my invention, l

4 claim 1. A-spring seat comprising abase, springs arranged on said base, a seat bottoni arranged on said springs, a back secured to said seat bottom, a guide arranged adjacent said back near each side thereof. brackets secured to said back adjacent said guides, a pair of rollers carried by each of said lill@ bracket and engaging opposite sides of said guides, the axes of sald rollers being arranged parallel to said back, and a roller carried by each of said fbrackets, the axes of said last named rollers being arranged at right angles to said back and adapted to engage the Inner faces of said guides.
